Specification of Letters Patent.

Patented Feb.16,1915.

Application filed March 7, 191%. Serial No. 682,116.

To all whom it may concern:

Be it known that I, HENRY W. ONEILL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Telautographic Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part or the same.

This invention relates to improvements in telautographs of the variable currentstrength-type, such as shown and described, for example, in.Let-ters Patent of the United States No. 954,150, granted to George S. Tiffany April 5, 1910.

The improvements of the present invention have reference particularly to means for vibrating the pen 1noving, ')arts in the receiving instrument so as to reduce frictional resistance to the movement of such parts while the instrument is receiving.

The improvements of the present invention have reference also to means for controlling, from the transmitting station, the movements of the receiving pen in the dis tant receiving instrument to and from the writing platen or record strip oi. that instrument as the transmitting tracer is moved to and from its writing platen or record strip.

In the accompanying drawingsFigure 1 is a diagrammatic view of a telautograph station, shown, for convenience, in transmit ting condition; and Fig. is a like view of another station, shown, for convenience, as receiving from the station illustrated in Fig. 1.

For convenience, I have, in these draw ings, illustrated the improvements constitoting my invention in connection with a telautographic system generally the same as that shown and described in detail in an application ofGeorge S. Tiii'any, filed Febl1ary 24, 1912, Serial Number ($79,598, but it will be understood, of course, that the present improvements are not to be limited totthe particular system there shown and d *c'ribed. It will also be understood that in rthe accompanying drawings I have illus- 'rheostat l, and from wire trated only so much of said system as is necessary to a proper understanding of the present improvements.

Each station comprises a transmitter and a receiver, and in the number, relative arrangement, and construction and operation of parts, one station is the counterpart of the. other. Therefore, in the following description. references will be made to either station, according as convenience in tracing circuits may dictate, corresponding refer-' ence numerals being used in both figures of the drawings, followed, however, in Fig. 2, by the reference letter a.

Each transmitter comprises a pair of rhcostats l, 2, included in a normally opened local circuit from a source of electric energy, for example, a motor generator 3, the negative pole or which is grounded-at 4t, this local current su iplying circuit being controlled by an electric iii-aster switch mechanism designated 5, as a whole, controlling movable contacts 6, 7, 8, which normally occupy the position in which. they are shown in Fig. 2, in which position the station is in receiving condition, and whcn out of that position, occupy the position in which they are shown in Fig. 1, where the station is in transmitting condition. Contact (3, in the position in which it is shown in Fig. 1, closes a circuit from generator traced follows: wire 9, Contacts 10, 6, wires 11, l2, 13, to right 12, by wires 15, 16, ll, to left rhcostzit 9, rheostat 1 by wires 18. 19, 130, and from left rhco it by \vi 21, 19, to the negative pole of generator 3. When contact 6 is in this position (Fig. 1), contacts 7, 8 engage a pair of stationary contacts 22, 23, cctively, thus closing the right and left tracer circuits from the transmitter of such station to the receiver of the distant station, as well as to its own receiver. This is so fully described in the aforesaid Titl'any application that it will be unnecessary to further describe it here beyond merely tracing the right and left hand tracer circuits as thus closed from the right and left rheostats and from right receiver of the distant station; arid also to describe,'in detail, in connection therewith, the improvements of the present invention by which the direct current of the generator 3 is converted into alternating currents for the purposes of vibrating the pen moving parts of the receiver, and also effecting the movements of the receiving pen to and from its writing surface. Such circuit, for the right line, consists of roller contact 24, tracer arm 25, wires 26, 27, contact 22, contact 7, wires 28, 29, 30 (Fig. 1), wires 30, 29, 28 contact 7, contact 31, wire 32 wire 34, pen moving coil 35, and wires 36, 37, and 19" to ground at 4, Fig. 2. Such circuit for the left line consists of roller contact 40, tracer arm 41, wires 42, 43, 44:} contact 23, contact 8, wires 45, 46, 47 (Fig. 1), wires 47, 46, 45, contacts 8, 48, wire 49, left relay 50", (controlling certain local circuits in the receiver), wire 51*, pen moving coil 52, wires 53, 54, andv 19 to ground at 4, Fig. 2.

and left lines; this, in turn, being dependent upon the extent and direction of the lateral movements of the transmitting tracer 55, and, therefore, the positions of the roller contacts Qal, L0, lengthwise of their respective rheostats l, 2. ments of the coils 35 52, will, in turn, through connections which are diagrammatically shown, but need not be specifically described here, control the lateral movements of the receiving pen 59, corresponding in extent and direction to such lateral movements of the transmitting tracer 55. All this is so fully described in the aforesaid 'Iiifany application that further description thereof in the present case is unnecessary.

' The system as thus far described, pro- It will be understood that, as more fully vides merely for the lateral movements of described in the aforesaid Tifiany application, as the transmitting tracer 55 (Fig. l)

, is moved laterally in writing, currents, varying in strength in accordance with the position of the contacts 24, 40, lengthwise of their respective rheostats 1, 2, will be shunted into the right and left mainline tracer circuits just described; that the coils 35, 52 of the distant receiver (Fig. 2) will be moved rectilinearly thereby in one direction against the tension of springs (not shown), tending to move: them in the opposite direction on. the core 56 of the field magnet 57, which, with its pole pieces 58, provides a suitable magnetic field forsuchcoils; and that as so moved, the coils 35 and 52 will move the receiving pen 59 laterally overits Writing field in the same direction, and to the same extent, as the transmitter tracer 55 is movedlaterally by the operator at the transmitting station. The magnetic field just referred to is excited from the generator 3 of Fig. 2 through a local circuit consisting of wire 9*, contact 10", wires 60 61*, a lock magnet 62 (of a unison switch group fully described in the aforesaid Tifi'any application), wire 63', the windings of field magnet 57, wires 6t, 65, 66, spring contact 67 mounted on but insulated from armature 68 of left hand relay 50, contact 69, and vwires 70*, 71 54 and 19, to the negative pole of the generator 3. This local circuit is opened and closed at a given station, as Fig. 2, at the contacts 67, 69, and. is so closed when another station (as Fig. 1) is transmitting to it and current is therefore on the left main line just, described from such other station, relay 50 being then energized and attracting its armature, 68 which moves contact 67 into' engagement with contact 69".

the receiving pen 59 in accordance with like movements of the transmitting tracer 55. The system, however, includes means for effecting the movements of the receiving pen 59* to and from its writing surface as the transmitter tracer is so moved, the means here shown for this purpose being those ,fully shown and described in the aforesaid Tiffany application, so that they need onl) be briefly described here. They include, (referring, for convenience, specifically to Fig. 2, as that station is receiving) a polarized pen lifter relay 75*, a pair of relatively loose contacts 76, 77 inclosed in a tube 78, mounted on a diaphragm 79 avhich is vibrated by the relay '75 when the transmitter tracer 55 rests upon and depresses the transmitter platen switch 80, and a pen lifter electromagnet 81, the energization and dei nergization of which is effected through contacts 76 7'? by the relay 75, so as to effect the movement of the receiving pen 59 respectively from and toward its record strip. The pen lifter magnet 81* is included in a branch of the field magnet local circuitheretofore described, such branch circuit being traced as follows: Wire 82 from field magnet 57, pen lifter magnet 81", wires 83, 8 h, contact 76*, contact 77, wires 8?, 66, contacts 67, 69, and wires 7O", 71, iii, and 19, to the negative pole of generator 3. As fully described in the aforesaid 'liffany application, the contacts 76, 77, included in this branch circuit, engage each other at their inner ends inside the tube 78, and one 01"- them is loose relatively to the other, so that when diaphragm 79 is vibrated, such contact will be vibrated relatively to the other contact, and thus, in effect, break this branch circuit and denergize the pen lifter magnet 81*, with Such rectilinear movewith. contact 1022, condenser 100 will continue to hi; ch Current will at the same time, hoivm' r, pass through magnet 101 by way of Wires 1051, 110, and .20, and when it rem-hrs 21 point sufiicient to overcome the re sistnncc to inmemcnt of its arnmture 103, it "i utiruct said urmuturm thus breaking rust troin current su 'iplying Wire. 16 tin: ronliz'nsnr 100, which will then irgc to ground or to the negative pole turn NFL and wires 110 Q0.

as uinmiurc also converts the direct current of generator 3 traversing the right line into alternating waves which are directed by an impedance coil 120 over the left line to the dis- ,tant receiver. Some impeding means is necessary in this line for diverting their waves or directing them through relay For this purpose I preferably utilize the relay 50 included in this line circuit; the impedance of such relay and of coil 52* being such that these alternating waves are backed or forced thereby over wire 87*, through pen lifter relay 75 and thence by Wire 90, condenser 91, and wires 92*, 37, and 19, to ground at 4*. These alternating waves produce in the relay 75 a vibratory condition causing it to alternately attract and repel with great rapidity or frequency the diaphragm 79, with the result that the relativel y loose contacts 76 77*, carried thereby, will be vibrated, one relatively to the other, so as to, in effect, break the circuit (including Wires 82 83, 8 contacts 76, 77, and wire 85) through the pen lifter magnet 81, which thus becomes deenergized.

As the magnet 81 is thus deenergized, its armature and the pen rest 121 carried thereby are withdrawn from pen supporting or engaging position and the receiving pen 59 therefore moves into contact with its writing platen or record strip; all as more fully shown and described in the aforesaid Tiffany application.

While I prefer to use the impedance coils 100, 120 at the transmitter for directing the alternating waves therefrom to the receiver, and to utilize the relay 50 for directing such waves, at the receiver, through pen lifter relay 75*, my invention, broadly considered, is not to be limited thereto, as various other means, either in the way of special devices or special construction of the devices usually present in or connected with the main line or lines, may be used for the purpose.
